IMPROVEMENT IN MACHINE FOR REMOVING- LINT FROM COTTON-SEED. w

The Schedule referred to in these Letters Patent and making prr. of the sama.

Be it known that I, WILLIAM F. PRATT, of East Bridgewater, in the county oi' Plymouth, and State of Massachusetts, have invented a new and useful Machine for' Removing the Down or Felt from the Gotton-Seed after it has been ginned; and I do hereby declare that the following is a full and exact description thereof, reference being had 'to the accompanying drawings, and to the letters of' reference marked thereon. g

To. enable others skilled in the art to makeand use my invention, I will proceed to describe its nature,

The nature of my invention consists in combining, with a series of circular saws and a hopper, a tluted roll, said roll serving, as it revolves, to turn the seed over and over,-and thus cause all parts of them to be acted upon by the teeth of the saws, said action continuing until all the down or felting in which all tufted seeds are enveloped is removed, and the seed left bare. Drawings. Figure l represents, inperspective, my invention. Figure 2 is a vertical section of the same. B, iig. 2, is a cylinder, provided with saws made and arranged on the drum or cylinder, as shown. These saws project into the hopper E, through gratevbars D, as shown in tig. 2.-

If desirable, the grate-bars may be dispensed with, and the saws be placed near to each other, in which case the saws themselves form one side of the hopper.

H is a i'luted roller, extending lengthwise through the hopper. The journals of this roller extend through the ends of the hopper, and have attached to them pulleys L, fig. 1`.

The belt R passes around theA pulley L, as shown in fig. 1, and serves to connect it with a pulley on the shaft A, so that the pulley L, and consequently the uted roller H, must revolve when the other parts of the machine are in motion.

N is a lever, pivoted at P, and carrying the tensionpnlleys M M, around which the `belt R passes, as shown in g. l.

This arm is provided'with a spiral spring, not shown in the drawings, which, resting in the hollow bracket O, serves to throw the lever up, and thus keep a constant tension on the belt R.

F is the seed-boardpivoted at S S, so that it mav be swung open when desirable.

The tinted roll H is placed at such a distance from the saws and the grate-bars, that it will not admit the v tufted seed to drop back between it and the grate, but will permit the seed, after it has been denuded, to fall to the lower part of the hopper, and thence through the opening inthe bottoni.

The uted roll H actsrupon the mass of seed to revolve it, and to bring each seed, and to subject all parts of the same to the action of the saws.

The process abovedescribed, of removing the down or felt from the seed, is entirely distinct lfrom ginning cotton.

This machine takes it after all the cotton is removed, and, by removing the downy covering or felting, which remains on the seed, prepares it for shipment, and also for feeding or making oil, and to prevent its heating when packed in bulk. It also greatly facil# itates the operation of planting the seed.

What I claim as my invention, and desire to secure by Letters Patent of the United States, is

The combinationof the roller H, constructed as described, with the saws and hopper, working substantially as described, and for the purpose set forth.
